Taiwan Manufacturer of Axial Type Multilayer Ceramic Capacitors
NPO : Temperature compensation type, with little or no change in capacitance with variation in temperature.
Hence, they are used in radio-frequency oscillators, precision timing circuits, ultra stable amplifiers,…...etc.
X7R : Temperature stable type for by-pass and decoupling in radio and television receivers, computers, servo systems,audio tone, and coupling,…...etc.
where moderate capacitance variations are permissible and dissipation factor is not critical.
Z5U / Y5V : General type for by-pass and filtering application.
